For a year our dog loved him like family. Then one afternoon he sank low and growled at the one man he'd never feared. I should have listened sooner.

I went out for fresh air after a bad day. Two blocks from home, parked in a driveway I knew too well, was a car I'd recognize anywhere.

My husband automated his life down to the minute. One scheduled text on the wrong day told me everything he had been hiding for two years.

He deleted the app, cleared his history, covered every track he could think of. He just forgot the one inbox we had always shared.

I woke at 4 a.m. certain of something I had no proof of. By breakfast I had the proof, and I wished I'd never gone looking.

My team works remotely, so I live inside our chat app. One Saturday, half-asleep, I noticed a colleague go active at 4 a.m. Then I noticed who else did.
